In general, crack fillers last for about two years on average. That timeline can be shorter if you have extremely harsh winters or longer if you live in a mild climate.

In general, water-based driveway sealers are considered the most eco-friendly option. Products that utilize water, limestone, and some basic binding agents have lower VOC levels and odor levels compared to sealants made with oil or tar. In recent years, soy-based driveway sealers have become available for homeowners who want fully VOC-free driveway sealers.

To maintain your asphalt driveway, add a new coat of sealant every three to five years. Pricing varies, but you will pay about $0.08 to $0.50 per square foot from start to finish. You can also choose to add a fill-and-seal layer that includes a layer of aggregate to fortify a damaged top layer of asphalt.

While blacktop is a type of asphalt, the terms should not be used interchangeably, as not all asphalt qualifies as blacktop. The primary differences are in their composition, production process, and ideal applications. Blacktop contains more stone than other types of asphalt and is heated to a higher temperature during production—300°F or more—while hot-mix asphalt is heated to between 275°F and 300°F. The ratio of bitumen (a tar-like crude oil) is a key differentiator, though sources vary: some state blacktop has less bitumen, making it less durable, while others claim it has a higher ratio. Due to these differences, asphalt is generally more durable and better for high-traffic areas like highways and streets, while blacktop is more suitable for playgrounds and residential driveways. For a driveway project, it is best to consult a professional to determine the most appropriate material.
